`Wbiplot`

produces a biplot with any weight distribution between Row and Column markers.
This way the full spectrum from perfect row resolution (Row-metric preserving biplot)
to perfect column resolution (Column-metric preserving biplot) is available.

`df` |
a dataframe with numeric values only |

`numer1` |
numerator of first exponent (can be a decimal) |

`denom1` |
denominator of first exponent (default: 1) |

`numer2` |
numerator of second exponent (can be a decimal) |

`denom2` |
denominator of second exponent (default: 1) |

`cx` |
graphical magnification factor (default: 0.5) |

This function makes use of function `Matpow`

from package powerplus to
be able to raise any valid matrix (see `Matpow`

documentation) to any real power between 0 and 1 included.

A biplot of a dataframe with the specified weights. Weights can either be supplied as two fractions, or as two decimal numbers.

# Exemple 1: Row metric preserving

# Exemple 2: Column metric preserving
Wbiplot(USArrests, numer1 = 0, numer2 = 1, cx = 0.6)
# Comparison with function \code{biplot} from package \pkg{stats}
biplot(princomp(USArrests), cex = 0.6)
# Example 3: Custom, 50-50
Wbiplot(USArrests, numer1 = 0.5, numer2 = 0.5)
# Example 4: Custom, 20-80
